PT3206N

Description: The PT3206N is a three-phase sensorless brushless DC motor driver IC designed for low noise and low voltage applications.It drives the motor sinusoidally, giving low noise performance. The PT3206N has useful functions such as start-up circuit, Pulse Width Modulation (PWM) speed control, RD\FG output for different control applications, as well as protective features such as lock and thermal protection. PT3206N is best suited for silent applications such as game consoles or CPU fans. It is available in DFN3x3- 10 package.
Protection functions of PT3206N are comprehensive, including lock protection and automatic recovery, thermal shutdown. These prevent the control circuits and the motor from being damaged, particularly under stressed applications and demanding environments.
